Turbo sizing and fuel management will be your hot spots to be successful or a disaster. I can tell you a blow through carb is simple but a terrible driver and you will regret it. So you will want to go with a fuel injection set up but if you cheap out there then you will be saddled with weird problems. If you can swing it buy a magnum motor complete out of the junkyard and blow through it and use the Holley terminator X system to manage. Next up is turbo sizing. This is critical. There is so much to turbo sizing it would take a few pages to contain the response. Personally I would call Comp turbo or Precision and work with them to find the right size. It will not spool in the appropriate time but it will have cooler intake air temps which will help tremendously in staying out of detonation. You will also want to use water/ meth injection for the same reason. Most likely a 300 hp 360 out of a truck will make 450hp with 7psi and probably make 700 LB/FT which will be really hard on the rods and cast piston. So maybe the goal would be 4 psi of boost with a stock bottom end.
